The undefeated Ninja defends her number one ranking against the number four challenger. Isis outweighs the Ninja, and is undefeated vs. lighter opponents. However the Ninja is not ready to simply let Goddess upset her. The Goddess, on the other hand, is in prime shape and ready to fuck the Ninja hard if she wins. Round four consists of the loser being made to worship the winners feet and then getting fucked hard into submission.
